Trawl hydrophone
The hull mounted hydrophone for trawl operations has a 50 degrees horizontal beam
and a 30 degrees vertical beam to provide the system with optimal reception from
the sensors on a bottom or pelagic trawl.
This specific beam pattern is especially suited for trawling.
Portable hydrophone
A portable hydrophone is also available. It is designed as a temporary solution until a
fixed hydrophone can be installed at the vessel’s next planned dry docking. It has an
omnidirectional beam and a 50 meter integrated cable.
The cable is supplied on a reel for convenient retrieval and stowage, and is equipped
with a plug for easy attachment to the Sensor Receiver. The cable is sheathed in
polyurethane providing robust external protection to compliment its 150 kg tensile
strength.

Hydrophone Splitter
In order to supply more than one sensor receiver with the sensors signals received through
the trawl hydrophone a hydrophone splitter must be used.
A hydrophone splitter has to be used for splitting the hydrophone input into two hydrophone
outputs.
